In VB6 I can declare a method parameter as optional.
Is there some way of doing this in C#?

Not exactly. There are two things you can do:
- Declare two methods, one with the optional parameter and one
without. Have the one without call the one with and pass in
a default value for the "optional" parameter
- Use parameter arrays. This isn't quite the same thing, but
you should probably know about them.
See 10.5.1.4 in the C# language specification on how to use
param arrays.

I'd absolutely prefer the first!
